make the batard suffer a lil bit

Hiii so I'm looking for some yaoi mangas/webtoons a little bit angsty. Where there is some unrequited love, and lot of jealousy... Or the be precise a story where the seme/uke is remorseful and feeling bad after being mean and treating his "ex-lover/sex partner" like shit when they have interest in other people.

A little bit in the style of bj alex, the 2nd couple of banana scandal, kiss me liar etc..

I want the asshole person to suffer pls. (๑•ㅂ•)و✧
